Cisco IPSEC VPN Client over WLC Guest-WLAN interrupts

[d.novakovic]

Hello

some strange issue when a wlan client is connected to guest-wlan (with web-auth from wlc controller) and is starting common client remote access ipsec vpn connection to a target on the internet.

The vpn client connects successfully, but there are interrupts after a while. when the user goes to internet via umts, the vpn connection is not interrupted - so it looks like it has to do with the wlc.

What about packet size - can this cause the issue?

so again -

1. client connects to guest-wlan via wlc

2. guest authenticates via web-login

3. guest starts cisco ipsec vpn cleint

4. client successfully starts vpn session

5. after some time, the vpn is terminated

Any idea? Thanks

When the VPN Session is terminated are the users presented with the web-auth page again? If so under controller menu there is a session timeout value, I believe the default is around 30 minutes.
